1. organize your mod in a folder and inside that folder make the following folders battle for your scene.bin flevel for your flevel.lgp or flevelchunks kernel for your kernel and kernel2 and any other of the folders that would be in direct mode for any other changes.

4. refresh your list and the iro will be at the bottom of the list. activate and test to make sure it works

5. upload to a file hosting service like mega, mediashare, Nexus, etc.

6. make a thread about your mod, including what it does, the link to get it, and install instructions (for iro it will be just download the iro and either place in your ff7/mods/7th heaven folder or import from iro library)

There are more steps that can be done to add a thumbnail to your iro, give it config options in 7th heaven, and a few other things. If you need any of those just unpack another similar IRO and look at how they organized the mod.xml
